C# 枚举使用和对应说明获取实例

1、定义枚举

    /// <summary>
    /// 订单状态
    /// </summary>
    public enum OrderState
    {
        待支付 = 1,
        待处理 = 2,
        配货中 = 3,
        已发货 = 4,
        已取消 = 5,
        已签收 = 6,
        配送失败 = 7

    }

    public enum ImageFoderType
    {
        [Description("Temp")]
        临时图片 = 0,
        [Description("GoodsImg")]
        商品图片 = 1,
        [Description("GoodsColorImg")]
        颜色图片 = 2,
        [Description("banner")]
        广告图片 = 3,
        [Description("ShowImg")]
        晒单图片 = 4

    }

2、根据枚举值获取枚举名称

 public static string GetOrderState(int OrderStateId)
    {
        string _name = string.Empty;
        int _status = 0;
        if (OrderStateId > 0)
        {
            _status = OrderStateId.ToString().ToInt();
        }
        if (Enum.IsDefined(typeof(Enums.OrderState), _status))
        {
            _name = ((Enums.OrderState)_status).ToString();
        }
        return _name;

    }
 

3、获取枚举对应说明文字

/// <summary> 获得某个Enum类型的中文，从description中读取
    /// </summary>
    /// <param name="enumType">枚举的类型</param>
    /// <param name="val">传入的值</param>
    /// <returns></returns>
    public static string GetEnumCNNameFromEnum(Type enumType, object val)
    {
        string enumvalue = Enum.GetName(enumType, val);
        if (String.IsNullOrEmpty(enumvalue))
            return "";
        FieldInfo finfo = enumType.GetField(enumvalue);
        object[] cAttr = finfo.GetCustomAttributes(typeof(DescriptionAttribute), true);
        if (cAttr.Length > 0)
        {
            DescriptionAttribute desc = cAttr[0] as DescriptionAttribute;
            if (desc != null)
            {
                return desc.Description;
            }
        }
        return enumvalue;
    }
